Hugo Chavez once said "the American empire is doing all it can to consolidate its system of domination."

"(W)e cannot allow them to do that. We cannot allow world dictatorship…"

"What type of democracy do you impose with marines and bombs?"

America "doesn't want peace. It wants to (expand) its system of exploitation, of pillage, of hegemony (worldwide) through war."

On Friday, thousands of Venezuelans officially presented up to 11 million anti-imperial signatures - collected through a petition denouncing Obama declaring Venezuela an "extraordinary threat (to US) national security and imposing illegal sanctions on its targeted officials.

President Nicholas Maduro called the petition proof of "the history of the people of Simon Bolivar…evoked, and it remains awake and alert."

"Venezuela is not alone," he stressed. He presented the petition symbolically to Summit of the America's participants. He intends sending it to Washington through diplomatic channels.

World leaders cannot "remain silent" about Washington's treatment of Venezuela, he stressed.

This weekend was the first time all 35 regional presidents attended a Summit of the Americas.
